    What effects occur in the liver in the sympathetic and parasympathetic divisions?

    • No effect in sympathetic, promotes synthesis of glycogen; increases bile secretion
    • Breakdown of glycogen into glucose, synthesis of new glucose, and realse of glucose into the blood; decreases bile secretion in sympathetic. Promotes synthesis of glycogen; increases bile secretion in parasympathetic
    • Promotes synthesis of glycogen; increases bile secretion; no effect in parasympathetic

    What are the effect of the urinary bladder in sympathetic and parasympathetic divisions?

    • Relaxation of muscular wall; contraction of internal sphincter in sympathetic and contraction of muscluar wall; relaxation of internal sphincter in parasympathetic

    • No effect in sympathetic; contraction of muscular wall; contraction of internal sphincter in parasympathetic

    • Relaxation of muscular wall in sympathetic; no effect in parasympathetic

    Correct Answer
    A. Relaxation of muscular wall; contraction of internal sphincter in sympathetic and contraction of muscluar wall; relaxation of internal sphincter in parasympathetic
    Explanation
    In the sympathetic division, the effect of the urinary bladder is the relaxation of the muscular wall, which allows for the storage of urine, and the contraction of the internal sphincter, which helps in the prevention of urine leakage. On the other hand, in the parasympathetic division, the effect is the contraction of the muscular wall, which aids in the expulsion of urine, and the relaxation of the internal sphincter, which allows for the passage of urine from the bladder.

    What are the effect of the Heart in sympathetic and parasympathetic divisions?

    • Increased heart rate and increased atrial and ventricular contraction in sympathetic; no effect in parasympathetic

    • Decreased heart rate and decreased atrial and venticular contraction in sympathetic; increased heart rate and increased atrial and ventricular contraction in parasympathetic

    • Increased heart rate and increased atrial and ventricular contraction in sympathetic; decreased heart rate and decreased force to atrial contraction

    Correct Answer
    A. Increased heart rate and increased atrial and ventricular contraction in sympathetic; decreased heart rate and decreased force to atrial contraction
    Explanation
    In the sympathetic division, the heart rate is increased along with increased atrial and ventricular contraction. This is because the sympathetic division is responsible for the "fight or flight" response, where the body prepares for action by increasing heart rate and cardiac output. On the other hand, in the parasympathetic division, the heart rate is decreased and the force of atrial contraction is also decreased. The parasympathetic division is responsible for the "rest and digest" response, where the body conserves energy and slows down bodily functions.

    What are the effect of the salivary glands in sympathetic and parasympathetic divisions?

    • Increases secretion in sympathetic; decreases in parasympathetic

    • Decreases secretion; increases secretion in parasympathetic

    • No effect; decreases secretion in parasympathetic

    Correct Answer
    A. Decreases secretion; increases secretion in parasympathetic
    Explanation
    The salivary glands are innervated by both the sympathetic and parasympathetic divisions of the autonomic nervous system. Sympathetic stimulation generally leads to a decrease in salivary gland secretion, while parasympathetic stimulation increases it. Therefore, the correct answer is "decreases secretion; increases secretion in parasympathetic."

    What are the effect of the gallbladder and ducts in sympathetic and parasympathetic divisions?

    • Storage of bile in gallbladder in sympathetic; release of bile into small intestine in parasympathetic

    • Releases bile into small intestine in sympathetic; store of bile in gallbladder in parasympathetic

    • No effect; release of bile into small intestines in parasympathetic

    Correct Answer
    A. Storage of bile in gallbladder in sympathetic; release of bile into small intestine in parasympathetic
    Explanation
    The correct answer is "storage of bile in gallbladder in sympathetic; release of bile into small intestine in parasympathetic." In the sympathetic division, the gallbladder stores bile, while in the parasympathetic division, bile is released into the small intestine.

    What are the effect of the kidney in sympathetic and parasympathetic divisions?

    • Decreases production of urine in sympathetic ; no effect in parasympathetic

    • Increased production of urine in sympathetic; decreases production of urine in parasympathetic

    • No effect; decreases production of urine in parasympathetic

    Correct Answer
    A. Decreases production of urine in sympathetic ; no effect in parasympathetic
    Explanation
    The correct answer is "decreases production of urine in sympathetic; no effect in parasympathetic." The sympathetic division of the autonomic nervous system is responsible for the "fight or flight" response, which includes the release of stress hormones and increased heart rate. In this state, the body conserves water by decreasing urine production through the action of the kidneys. On the other hand, the parasympathetic division is responsible for the "rest and digest" response, which does not involve the release of stress hormones. Therefore, it does not affect urine production.

    What effects occur on the seat glands in the sympathetic and parasympathetic division?

    • No known effect; increased sweating

    • Increased sweating; decreased sweating

    • Increased sweating; no effect

    Correct Answer
    A. Increased sweating; no effect
    Explanation
    In the sympathetic division, the seat glands experience increased sweating due to the activation of the sympathetic nervous system, which is responsible for the "fight or flight" response. On the other hand, in the parasympathetic division, there is no known effect on the seat glands, as this division is responsible for the "rest and digest" response. Therefore, the correct answer is "increased sweating; no effect."

    What effects occur in the radial muscle of the iris of the eye in the sympathetic and parasympathetic divisions?

    • Dilation of pupil in the sympathetic, no effect in parasymapathetic

    • Constriction of pupil in sympathetic, dialation of pupil in parasympathetic

    • Dilation of pupil in sympathetic, constriction of pupil in parasympathetic

    Correct Answer
    A. Dilation of pupil in the sympathetic, no effect in parasymapathetic
    Explanation
    In the sympathetic division, the radial muscle of the iris of the eye undergoes dilation, leading to an increase in the size of the pupil. This is due to the activation of the sympathetic nervous system, which prepares the body for "fight or flight" responses. On the other hand, the parasympathetic division does not have any effect on the radial muscle of the iris, thus there is no change in the size of the pupil. The parasympathetic division is responsible for promoting rest and digestion.
